Found this researching lighting. Thought that it might be of some interest to others when they need new bulbs/ballasts

did anyone see this at reefcentral?? there was a big debate about the meter he used to measure par.. the meter would be accurate for light around the 10-13k.... so all the 15-20k measure werent accurate... thas why their par is low....
